T @ZZ whom if 'may concern:

Be it known thatI, CARL F. CAPELL, a citizen of the United States, residing at Los Angeles,

. bers.

in the county'of Los Angeles' and vState of California, have invented new and useful Improvements in Hydrocarbon Burners, of which the following is a specification.-

My invention relates to a burner designed to vaporize liquid hydrocarbon fuel and commingle the vapor with air in sufficient quantity to burn; and the object thereof is to produce a burner in which the vapor of the liquid hydrocarbon fuel is dischargedl into two separate miXingchambers, one of which( has a much greater capacity than theA other and in which the capacity of the burner may be controlled, while in the smaller chamber the fire is constant as long as the burner is in use. I accomplish this object by the mechanism described herein, and illustrated in the accompanying drawings, in which- Figure l is a plan of my burner, partly in section, the sectional part being taken on line l l of Fig. 2. Fig. 2 is a verticalsection on the line 2 2 of Fig. 1, a small portion being shown in elevation. Fig. 3 is an end view partly in section and partly broken away for clearness of illustration.

' In the drawings, A is the supply-pi pe, which is connected with a suitable reservoir (not shown) of liquid hydrocarbon fuel. This supply-pipe opens into the vaporizing-chamber B, which is composed of .one or more cham- If more than one chamber is used, the channel through the chamber is connected at opposite ends, as shown in Fig. 1, in which Fig. l I have shown three chambers, as I pre-v fer that number; but a less or greater number may be used, if desired. In the ends of these chambers are plugs C, which may be removed for the purpose of cleaning, and in each chamber I place a piece of non-inflammable rope or cord I), upon which impurities carried by the liquid fuel collect and which may be removed from the chamber and cleaned whenv the plugs areout. To the end of the chamber farthest from the supplypipe is connected conveyer-tube E, which is provided with branches F and G. The branch F is provided with a needle valve H to control the flow of vapor therethrough, which is discharged into `the air-tube I, which tube opens into the mixing-chamber J, the top of which is provided with slots K, through which the commingled air and vapor passes and is burned yat the top thereof just below one end of chamber B, vsaid end being the end nearest to the outlet from said vaporiZing-chamber. The

lower end of the conveyer-tube is provided with a regulating-valve L, whose stem L may be operated in any suitable manner to control the flow of vapor through branch G, which the channels N is provided with perforations R, through which air can pass to assist combustion.

In the operation of my burner a supply of liquid fuel is permitted to fill the starting-cup S, and it is then turned ofi'1 and the fuel in the cup lighted. As soon as the burner is sufficiently hot the supply of fuel is again turned on and the needle-'valve opened. The valve H is opened to its full extent, while the valveL is opened sufciently to supply enough vapor vto produce the necessary flame.

In order to protect the iiame from draft, I provide a frame T, which extends around and above the channels Nfand other parts of the mixing-chambers, as'shown. For convenience in construction I form the vaporizingchamber of the pipes U, which are screwed into fittings V and W. The fittings V are what may be termed double. fittings, and the fittings W are a single fitting, so that one of the pipes U may be screwed into the double fittings, and afterward the pipes on either side may be screwed into the double fittings and the single fittings screwed onto the pipes. The frame is provided with a removable plate T', which is removed when lthe vaporizingchamber is placed in position in the burner and is then replaced and fastened by screws IOO X, which serve to hold the plate to the other parts of the frame. The rear end of the littings pass through a hole in the frame. Inside of the frame the fittings are provided with flanges V and V, which prevent the further movement of the chamber through the frame. The front part of the frame forms an inclosure around three sides yand the topv of the conveyer-tube, so as to prevent the cool air from coming in contact with the parts which discharge the vapor into the air-tubes.

Chamber J has a slot K', which discharges the fuel toward the conveyer-tube, and the same burns around the tube, thereby keeping it hot and preventing the fuel from returning bacl; to its liquid state.

When the vaporizing chamber requires cleaning, by removing plate T it may be removed, cleaned, and replaced without interfering with any of the other parts, the supply-pipe being first disconnected.

Having described my invention, what I claim as new, 'and desire to secure by Letters Patent, is-

1. A hydrocarbon-burner comprising a plurality of tubes connected together having a liquid-fuel inlet at one end and a vapor-outlet at the other end; two mixing-chambers under said vaporizing-chamber having their tops slotted, one of said mixing-chambers being smaller than the other and being located adjacent to the vapor-outlet, and having one of the slots thereof adjacent to the vapor-tube to permit vapor to escape therefrom to burn around the vapor-tube whereby it is kept in a heated lcondition; cords of non-inflammable material in the tubes forming the vaporizingchamber; removable plugs in the ends of said tubes; air -tubes connected to said mixingchambers; a vapor-tube having a channel having two outlets connected to said vaporizingchamber, one of said outlets being adapted to discharge vapor into one of said air-tubes and the other outlet to discharge vapor into the other air-tube; a casing around said vaportube; valves adapted to control the discharge of the vapor from said outlets.

2. A hydrocarbon-burner having a Vaporizing-chamber composed of three vaporizingtubes alternately connected together at opposite ends; a liquid-fuel inlet at one end of said tubes and a vapor-outlet at the other end of said tubes; non inflammable cords in said tubes; removable plugs in the ends of said tubes; a vapor-tube having a channel having two outlets connected with said vaporizingtubes; a small mixing-chamber under the ends of said tubes adjacent to said outlet-channel, a larger mixing-chamber under said tubes having a central space and radiating channels extending therefrom, said miXing-chambers havingl slotted tops; air-tubes connected with said mixing-chambers to receive the discharge of vapor from the vapor-channels.

3.
